Great job today Charity! Congrats on the reduction and good instincts handling the low numbers.

And I promise, next time will be easier. You've done a good job on the SS documenting what you gave when. That will help in the future.
How was Zhoomie doing during the low numbers? We don't normally call it a hypo unless cats are exhibiting actual hypo symptoms.
I'd also like to comment on some of what was said today. This is in the
Sticky Note on Handling Low Numbers. First, HC was given first, and was absolutely the right thing to do, unless you know your kitty's response to carbs, and know that less could work. First of all, it's says use HC in the Sticky Note.

Two reasons here. First, when a caregiver is new to low numbers, you want to be cautious and start with the big guns first cause we don't know how carb sensitive the cat is yet. The idea between HC is that you want to get a decent bump in numbers, as the numbers could come down when the carbs wears off. Second, the low numbers occurred early on in the cycle. This was well before nadir, the insulin is stronger and still working to take the numbers down. Later in the cycle is when you can start playing with less carbs.
Carbs take 20-30 minutes to go from the plate to the blood stream. ECID - learn what works for your cat.
And just a PSA - new folks, if you haven't already, print off the Sticky Note on handling low numbers. Invariably there will be a time when the power is out or internet is down and your cat will go low. They just know the worst timing.
